To all whom it may concern.-

Be it known that 1, JOHN H. CnosKEY, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Ap aratus for Manufacturing Glass Articles, of which the.

. foryertically reciprocating and rotating the main carrying-stem. Figs. 5 and 6 are de tail views illustrating the mutilated gearing for transmitting intermittent rotating move- :ment to said shaft. Fig. 7 is a' detail view of the ratchet-arm for intermittently rotating the table.

My invention refers to improvements in apparatus for forming articles of plastic nature, as glass, the machine shown being particularly desi ned for the manufacture of in sulators for telegraph or other wires.

The present invention refers particularly to the mechanism for lifting the finished art1- suit-a else outof the mold and discharging them upon any suitable receiving means.

Referring now to the drawings illustrating the invention, .2 is the rotating table of the machine, provided with a plurality of molds 3, adapted to receive the molten glass and to mold the finished article under pressure of a lple plunger, as is the common/practice in this class of apparatus.

The machine generally is similar to theone shown and described in my prior application, filed June 10, 1904, hearing the Serial No. 211,904, and is provided with suitable means for intermittently rotating the table step by step, so as to bring the molds successively into proper position for being filled with the plastic material, ressing the material therein by the usual p ungers adapted to form the article, and to provide it with an interior thread, and to finally locate the molds in opened position at a point where, during the stationary eriod of the apparatus, the finished artic e may be lifted away and discharged. Ordinarily this operation is performed manually, and my invention is designed to provide means arranged to grasp the finished insulator, raise it, swing it around, and drop it upon an inclined chute or any convenient conveying means by Which the articles may be conveyed away from the machine. This result is secured by means of a vertically-reciprocating intermit tently-rotating spindle 4, mounted in'a suit able frame 5 in convenient proximity to the machine for cooperating with the per portion with a p urality, preferably three, of spidenarms 6, secured upon the uper portion of the spindle, as shown in Fig. 1, aving downwardlyextending stems 7 so located with relation to the center of each roper mold, the spindle 4 bein provided at its upthat these stems will vertically aline therewith during the non-rotating period of both the machine and the discharging device.

Secured upon the stem by nuts 8 or other wise, and preferably vertically adjustable thereon, are spring-arms 9 9, provided with gripping-terminals 10, having inwardly-proecting lips adaptedto engage under the top portion or cap of the insulator A, as clearly indicated in Figs. 1 and 21' The inner portions of the gripping-terminals are flared or inclined, as shown at 11, whereby they will slide down over the top of the article and automatically engage underneath its head, as will be readily understood.

For. the purpose ofraising the spindle 4 at the proper time and of lowering the grippingment of the table, the cam being so designed that it will cause the spindle 7 and its grasping-tool to gradually rise and will allow it to IOO drop downwardly over the insulator at theproper time. The cam then-immediately raises the spindle, carrying with it the insulater and lifting it freeoi the mold during its stationary'period, and the spindle 4 is then partially rotated in the direction of the arably threaded and row a, Fig. 3, a fraction of a complete revolution, preferably one-third when three arms are employed, so as to bring the too] of one arm and the suspended 'article into registering position with a receiving chute or carrier 16, upon which the article is to be dro pad, and to also bring the next adjacent tool into re ister with the next-mold to grasp the ins.

su ator therein. The as in and carryin tool of the loaded ar i n iis d esigned' to b opened at the time the spindle l drops for the next grasping operation, and for this purpose I tprovide a stationary abutment 17, mounte in arm 18 by means of a stem 19, preferrovided with securingt e stem abutment nuts 20 whereb adjustedto'the desired may be delicate hei ht.

S idingly mounted on the lower part of stem 7 and normally resting against a termimil collar 21 thereon is a yoke 22, carrying.

wheels 23, arranged to bear inwardly against the spring-arms 9, which, as shown, converge upwardly above said rollers,'so that when saidrollers are raised, or when, conversely, the

springs are lowered, the rollers being main-.

- engagement t erewith, as shown, into the segmental series of teeth 26, whereof meshes a corresponding series of segmental teeth 27 of a mutilated gear 28, mounted, on the inner end of shaft 29, carrying the constantly-ro- 'tating bevel-gear 14. By this means it will be seen that a one-third revolution is imarted to spindle 4 at the proper time to efiect the results just described. The spindle 4 is preferably provided with astud 30, carrying a terminal roller 31, normally resting u )on the edge of cam 12, and ,theweight of t e spindle and its superimposed mechanism is ordinarily sufiicient to effect the rapid downward drop, although gravity may be augmented by the use of a spring or counterweight, if necessary.

As thus constructed my device is capable of effective automatic 0 eration, quickly and securely grasping the 'nished insulators as they are brought into register within the opened molds, and they are raised, thrown around, and gently dropped upon the carrier- 15 wilhout danger of breakage or of interference with the other operative portions of the apparatus. spider-arms 6 maybe varied in number-as, for instance, two or four-in which case the actuating mechanism will be correspondingly changed.- It will be also understood that various other chan es or modifications may be made by the skilled mechanic to effeet the same result; but all such changes are to be considered as within the scope of the.

following claims. What I claim'is 1. The combination with a traveling mold, of a vertically-movable device arranged to It will be upderstood that the w enter downwardly within the mold and to grip the molded article, with means for raising said device and article and. for swinging them laterally away from the mold, substantially as set forth.

2. The combination with a traveling mold, of a vertically-movable device arranged to enter downwardly within the mold and to grip the molded article, with means for rais 4. The combination with anintei mittently rotatable mold-carrier and molds thereon; of a vertitially-reciprocating framework provided with c utch devices adapted to enter downwardly within the mold-cavity and to esp the finished article, raiseit, and swing 1t laterally away from the mold, with means for actuating said mechanism during the stationary period of the mold carrier, substantially as set forth. v

5. Apparatus for removing finished articles from glass-molds consisting of verticallydisposed spring-arms having gripping-terminals, a vertica ly-movable supportingdrame therefor, means for raising sa1d frame, and means for partially rotating it, substantially as set forth.

6. In applaratus for" formin articles of glassware, t e combination wit a rotatable mold-car1ie11:. and means for mtermittently rotating said carrier; of a vertically-movable spindle, means for raising and lowering said spindle, means carried on said spindle for engaging the finishedj article, and means for actuatmg sald mechanism in conformity with the travel of the mold-carrier, substantially as set forth.
